This is a very small matter, but I would be grateful if you made that a PPV-editable setting (although I vaguely wonder if more drop-down nodes are needed for the lumen settings as they’ve accrued more and more options).
While not a problem in most scenes, I’ve definitely seen situations where the large discontinuity between the very soft shadows of an area light look quite strange next to the razor-sharp lumen scene shadows. A toggle would be very nice
